NURSING-BOTTLE.

Specification of Letters Patent.

Patented Aug. 25, 1914.

Application filed April "19, 1913. Serial No. 762,267.

of the invention being to provlde a bottle of this character in whichthe nipple is firmly retained 'upon the neck.

Frequently the infant pulls the ni ple off the bottle and spills all ofthe mi k, thus necessitating refilling of the bottle and reclothing ofthe child. Several attempts have been made to secure an efficient andsanitary arrangement for securing the nipples in position' posit'velybut, to the best of my knowledge, no such construction has yet beenplaced on the market.

It is, therefore, the object of this invention to avoid the aforesaiddifficulties and to provide a positive lock for the nipple.

Further objects of the invention will appear as the followingdescription is read in connection with the accompanying drawing whichforms a part of this application, and in which Figure 1 is a sectionalview taken through the neck of the bottle and showing one form of thedevice. Fig. 2 is a similar view showing another form.

Referring more particularly to the drawing, 1 represents an ordinarynursing bottle having a neck 2 which is provided with an annular grove 3adapted to receive the head 4: on the lower end of the nipple 5. Thelower portion of the neck or that portion adjoining the body of thebottle is somewhat larger than the outer portion of the neck and isprovided with screw threads 6 to receive a locking collar or band 7which is .ceive the head of a nipple,

threaded thereon and is provided with an annular flange or extension 8which is adapted to closely fitthe nipple and hold the bead inengagement with the groove, the resilience of the nipple of courseassisting in this function. Fig. 2 shows the bottle similarly formed butthe band or collar 9 is not provided with the extension or flange 8, thecollar being long enough to extend up over the head of the nipple and isnormally arranged on the bottle neck and is screwed up over the nipple,whereas in Fig. 1 the band is threaded on the neck after the nipple hasbeen placed in position. .It will be noted in these figures that theupper portion of the neck is sufiiciently small to ermit the removal ofthe band when, it is necessary to clean the bottle.

' From the foregoing it will be seen that in all of the structuresdescribed the nipple is held firmly upon the neck of the bottle so thatit cannot be loosened up or accidentally removed by the infant.

What is claimed is In combination, a bottle rovided with an annulargroove in its neck a nipple having a head to fit said groove, anenlarged threaded portion on said neck below the groove, and acontinuous circular locking band threaded on the neck and adapted tohold said head within the groove, said band arranged to pass over the niple when the nipple is applied to the neo whereby the nipple can beremoved without removing the band.
